石墨烯是由碳原子紧密排列而成的具有单层二维蜂窝状的碳材料，是构建其他碳材料（零维的富勒烯、一维的碳纳米管、三维的石墨）的基本单元。由于其优异的电学、热力学、力学和光学性能使其能在电子器件、传感器、储氢。目前应用在锂电池电极，超级电容器，触摸屏，散热膜，导电膜，导电角，导电、导热、防腐涂料，催化剂，光学传感器，塑料和金属类复合材料，航空复合结构材料，风电风车结构复合材料，船舶复合结构材料等等有广阔的应用前景。本产品为采用直流电弧法制备（Carbon 2010,48,225-259; Nanotechnology 2010,21,175602,封面论文），产品为氮原子渗杂石墨烯，石墨片尺寸为100-200nm,含2~6个石墨层，无金属残留。
电弧法制备的石墨烯尺寸较小，作为锂离子电池负极材料时，锂离子的迁移路径短，因而具有出色的高倍率充放电性能（Nano Research 2010,3,748-756）。石墨烯与无机物的复合物有望应用于催化与能源等领域(Journal of Nanoscience and Nanotechnolo -gy 2010,10,6690-6693; Journal of Nanoscience and Nanotech- nology 2010,10,6748-6751)。
Graphene is a honeycomb-like sheet of carbon, and is basic unit to build other carbon materials (zero-dimensional fullerens、one-dimensinal carbon nanotubes、three-dimensional graphite). It’s excellent electrical, thermodynamic,mechanical and optical performance made broad prospects of it’s application in fields of lithium battery electrodes, supercapacitors, touch screen, thermal film, conductive film, conductive angle, electrical conduc- tivity, thermal conductivity,anti-corrosioncoatings,catalysts, photoe- lectric sensors, plastic and metal composites, aerospace composite structural materials, wind power windmill structural composites,marine composites structural materials. The product is prepared by direct current arc method (carbon 2010,48,255-259; Nanotechnology 2010,21,175602, cover paper), the product is nitrogen-doped graphene, size of graphite flake is 100-200nm, with 2～6 graphite layers and no metallic residue.
Arc process prepared graphene is small. When it is used as anode material for lithium-ion battery,because of the short migration path of lithium ion, it gained excellent high-rate discharge performance(Nano Research 2010,3,748-756). Graphene and inorganic complexes are expected to be applied in catalysis、energy and other fields.
